Rather than regret a new home purchase, choosing one part of it (one part at a time) and making an affordable change that would turn it into a place you really want to be woud be preferable -- even if that place is a patio in the yard ... a place outdoors to enjoy the fall weather and maybe enjoy creating it, too.
Pay attention to what rooms are on the east. Especially if you're a morning person, and if the view is reasonably good, you could make that room your first project begining with making it feel light and airy rather than gloomy.
You might talk with the pros about any concerns regarding moisture issues. I've been told that removing anything and everything the former residents may have thrown beneath the home -- (old flower pots, etc.) and putting thick plastic sheeting on the ground beneath older homes, covering the dirt entirely, can help forestall mildew issues. Crawling beneath the home after a rain (with plenty of light) gives you an opportunity to see of moisture is getting beneath the home.
One person I know literally dug out the several inches of loose dirt beneath their newly purchased home, foundation to foundation, before adding plastic sheeting because pets and/or wildlife appear to have been permitted to live/potty beneath the house. Investigating and addressing such things early on, particularly before the house is closed up to be heated for the winter, can save you a lot of grief later.
